Burnley's 4-1 thumping of Hull at the KC Stadium on Saturday - the club's first ever away win in the Premier League - has raised hopes of a great escape for Brian Laws' troops.
Although still four points adrift of safety, Duff told the Lancashire Telegraph: "It's been a long time since we won a game.
"Hopefully it will boost confidence and drag a few more teams in above us. Maybe they'll look over their shoulder a little bit more.
"We just need to keep turning in performances, and, ultimately, picking up wins. We're at the stage of the season where we need results, it doesn't matter where we win now though, we just need points.
"Hopefully we can get a couple more wins and see where it takes us."
